ham, in the -county of Lancaster, in the Kingdomof England, have invented certain new and useful Improvements in Combing-Machines for Combing Cotton, Wool, and other lFibrons Materials, of which the following is a specification.

This invention `of improvements' V1n comblng-machines for combing cotton, wool, and

j other fibrousmaterials consists in the application to such machines of mechanism to relieve the operatives attending to such ma-' chines of the labor hitherto involved in unweighting or relieving the detaching-rollers and the rollers of the `draw-boxes used in such machines of the pressure of the weights used therewith, as is necessary in order that .the-

. covered top rollers may not lbe injured bythe weights being left hanging on the rollers whensuch machines are not working, as during the stoppage of mills in which such machines are employed. Ify the weights are left hangingon .the rollers when the machines are not working,.the pressure 4on the top rollers tends to form flat places on them at the parts which rest von the'bottom rollers used with:

such top .rollers` -According to this .invention I provide for each roller., whether it be a roller .of the drawbox or a, detaching-roller which maybe required to be relived from time to time of the pressure of the weight or weights used therewith, adevice moved byacam or cams to enga ewiththeweight or Weights used with such rol er., so that such weight or weights may be raised and supported with little labor on the art of the attendant in charge ofthe com ing-machine and supported when raised for as long as .may be desirable; and I arrange the said device so that it may be operated` easily .and conveniently lby the attendant in charge ofthe machine in which it is employed. j

I have 'illustrated and described in the `accompanying .drawings and the description following one form of mechanism'by way of example .of the various arrangements which may be employedaccording to `this invention. p In the accompanyin drawings, Figure 1 is a .front elevation, part y inlongitudinalrvertical section, of so'much of acombing-machine as requisite 4forthe villustration of 4the form `of this invention, which is shown in the accompanying drawings by way of example. Fig 2 is a plan of the said portion of the said combing-machine with some parts omitted to obviate confusion. Fig. 3 is a transverse vertical section showing th'e said portion of the combing-machine as seen from the right hand of Figs. l and 2 and partly broken to show parts which would otherwise be hidden. Figs. 4, l5, .and l6 fare-elevations, partly transverse sections, taken onia plane parallel to that of Fig. 3 and showing on a larger scale than Fig. 3 and in three different 1positions .one of the cams usedaccording to this invention inthe form illustrated by Way of `exam- -ple in the vaccompanying drawings .and the arm acted upon by the said cam and .certain other parts used with such cam. v

In the drawings, a, Figsl and 3, is the bottom detaching-roller, which extends, as usual, through the several heads of the machine, the portion shown being that which is farthest from the place at which such detachving-roller receives motion andlisi supported and moved by the usual means, which being well known .to persons conversant with .comby ing-machines is' not-described in this specification. The bottom detaching-roller a is 1 omitted from Fig. 2 to obviatje confusion. The bottom detaching-roller a is ,arranged t0 act in the ordinary may in conjunction with the usual leather-covered top detaching-rollers I), which are mounted and operated 1n the hooks c are respectively provided in the ord'i-v 95 nary :way with projections d, by which When removed from the top detaching-rollers b they may be made to rest upon projecting supports e, provided to receive .them on the brackets f, supporting some ,of the mec-hanism used with the said portion of the topdejtaching-roller a. Y

.Connecting devices .ofany suitable kind g, which in .thecase illustratedfare chains I, connected to the hooks c. and provided with hooks h and ,guided by means of pulleys i, are provided to `transmit to the top detach- `jing-rollers l) the pressure `of theweights j lused therewith, of which weights only one is shownin `the drawings. As will be herein- IOO IIC)4 after mentioned, each weight y' is provided with an ear or projection lc at each end for the purpose of this invention as embodied in the arrangement illustrated. A similar weight similarly supported is provided for each top detaching-roller b.

m m are the top rollers of the draw-box, which are mounted and arranged to act in conjunction with bottom rollers n in the ordinary way. In conjunction with each of the top rollers m there are provided two hooks of the ordinary kind connectedto a crossbar p, to which is connected a hook g', supporting the weight r used with such top rollers m, there being in each combing-machine three or more weights r, each serving to eX- ert pressure on one of the threeor more top rollers m employed therein. In the case illustrated there are four top rollers m, and consequently four weights 1'". For the purposes of this invention as embodied in the arrangement illustrated each of the weights 9"' is provided with a slot s, as will be hereinafter described.

j During the working of the machine the weights y' are supported by the top detaching-rollers b with which they are respectively used, and the weights r are supported by the top drawing-rollers m with which they are respectively used, and apart from the inevitable wear to which they are subject the leather coverings of the top detaching-rollers b and the toprollers m of the draw-box receive no injury from the pressure to which they are subject. If, however, the machine be stopped, and especially if it be stopped for a lengthened period while the weights j r remain supported by the rollers b m with which they are respectively used, the leather coverings are injured by hollows or flat places being formed in them at the parts at which they are pressed upon the metal rollers used therewith. Hitherto to relieve the top detaching-rollers l) and the top rollers m of the pressure of the weights y' 1 respectively used therewith ,has been aninconvenient and laboriousoperation, which by reason of being inconvenient and laborious has been often neglected by the attendants in charge of combing-machines to the detriment of the leather-covered rollers I) m and the work done by such machines. According to this invention I provide devices which, being moved into and held in a suitable position, act uponl the weights which it may be desired to put out of action from time to time and support the weight thereof and prevent them from continuing to exert pressure upon the rollers with which they are respectively used. In the arrangement illustrated by 4way' of example in the accompanying drawings means are provided by which at times both the weights used with the top detaching-rollers l) and the weights r used with the top 'drawing-rollers m can be relieved and by szasefi whichat other times only the weights 1 used with the top drawing-rollers 'In may be re' lieved or put out of action on the rollers used with them. In the said arrangement arms or levers t are provided to engage with the weights used with the top detaching-rollers t, there being two arms or levers t for each Weight As shown, the weights are provided with projections 7c for the arms or levers tto engage with, and, as is clearly shown in Figs. 4, 5, and 6, the arms t are provided. with rounded bearing-sui faces u, bounded at each end by substantially vertical surfaces i), so as to be furnished with seats to receive the said projections k. In the arrangement illustrated in the drawings the said arms t are shown as secured upon a shaft w, fast upon which is an arm as, provided with a bearingsurface 2 to be acted upon by a cam 2.. As shown, the said shaft w is mounted in brackets 3, secured to the rail 4, which forms part of the framework of the machine. The cam 2, as shown, is secured upon a shaft 5, capable of being turned in bearings formed one in a bracket l5, secured to the end frame (j ofthe machine, and the other in a bracket 7, secured to the rail 4, and is formed with a surface S, which when such cam 2 is turned in the direction indicated by the arrow A from the position in which it is indicated in Figs. 3 and 4 to the position in which it is indicated in Fig. 5 acts upon the bearingsurface z of the arm a; and depressing it raises the arms t, so that the bearing-surfaces u thereof act upon the projections 7c, formed on the weights j, used with the top detaching-rollers b, and raise and support such weights so as to relieve such top detaehingrollers b from the pressure of the wieghts When the cam 2 is turned in the direction opposite to that indicated by the arrow A from the position in which it is indicated in Fig. 5, the arms tcease to support the weights so that suehweights are again allowed to exert pressure upon the top detaching-rollers b.

The surface 8 of the cam 2 is so formed that when the said cam 2 is turned in the direction opposite to that indicated by the arrow A, from the position in which it is shown in Figs. 3 and 4 to the position in which it is shown in Fig. 6, the arm x will not be depressed and the weights will not be raised.

The shaft 5 in the arrangement illustrated is adapted to be turned by means of a wormwheel 9, secured upon it, and a worm 10, secured upon a shaft 11, which is capable of being revolved in bearings formed in a bracket l2, secured to the end frame 6 of the machine, and is provided with a handwheel 13, so that it may be conveniently turned. For convenience the shaft 5 is made to pass through the slots s of the weights 1.

The description already given herein describes the mechanism used in the arrangement illustrated in the drawings for relieving `r ,thei'top detaching-roller's b ofthe 'pressure of f' the weights y', and if it beconsidered desirable the p'arts already described may be ern ployed for the said purposewithout the use of the other mechanism, which in the arrangement illustrated is provided in order that the 4weight?q is for the purpose of this invention provided with a slot s. The slots s besides serving for the passage of the shaft 5 serve to receive a rod 14, which being arranged to be raised and lowered serves in the arrangement illustrated as the device for raising and supporting the weights r, so as to relieve the top rollers m of the draw-box ofthe pressure 'eX- erted thereby in the ordinaryworking ofthe machine.

. to be` raised for the said purpose either about one end or as a whole, as shown, and in any` s 15, which are provided with openings 16,

which receive the rod 14 and guideit when it is moved upward and downward. The rod 14 is formed at its ends with necks to enter such openings 16.

Each of the cams, as shown, though not necessarily, is provided with two surfaces 17 18 to act upon the rod 14 and raise it when the said cams 2 are turned in either direction from the positions in which they are indicated in Figs. 3 and 4. In,the positions in which they are indicated in Figs. 3 and 4 the cams 2 present their parts 19 which are `of least radius to the rod 14, thereby allowing the weights r to hang free of such rod 14. In being turned in either direction from the position in which they are shown in Figs. 8 and 4 the cams 2 raise the said rod 14 by means of their surfaces 17 or their surfaces 18, according to the direction in which they may be turned, and by raising the said rod 14 bring it against the upper ends of the slots s in the weights r and cause it to act upon the said weights r and raise them, so as to relieve the top drawing-rollers m oi the pressure ordinarily exerted thereon by the said weights r. At the end of each surface 17 or 18 which is most remote from the part 19 of the cam 2 on which itis formed there is formed a hollow 20. The hollows 20, receiving the rod 14 when the cams 2 are turned in either direction to the extent necessary to raise the Weights acted upon, serve to hold the said vthe said weights so raised.

The said rod 14 maybe arranged weightsin 'a raised position and make such i rod 14 hold the cams 2in Each cam 2 is provided with the two surfaces 17 18 to act on the rod 14, so that by the cams 2 being turned in the direction indiposition to keep cated by the arrow A, Fig. 4, into the position shownin Fig. 5 both the top detachingrollers b'and thetop drawing-rollers 'm may be relieved of the pressure oi the weights and r, respectively, used therewith, while by the cams 2 being turned in the direction opposite to that indicated by the arrow A,.Fig. 4, into the position shown in Fig. Gnthe top drawing-rollers fm may be relieved of the pressure of the weights r, `while the top de-Y taching-rollers b remain subject to the pressure of the weights jused therewith, as is de sirable in order that the draw-'box rollers may be accessible for the removal of rollerlaps or other purposes without interference with the grip of the detaching-rollers and the other parts with which they cooperate in the combing of the fibrous material being oper-v ated upon. By the hand-wheel 13 being turned in one direction or lthe other the Op* erations of relieving either -the rollers m of the draw-box alone or the .rollers/m oi the draw-box and the top detaching-rollers b of the pressure of the weights used therewith and also `of againreapplying pressure to such rollers can be easilyfand conveniently accomplished, and these operations being made easy and convenient the damage to the rollers hitherto due to the neglect oi' the attendants to relieve such rollers of pressure is obviated.
